Title:
FLAP TABLE
Document Type and Number:
Japanese Patent JP2010252867
Kind Code:
A
Abstract:

To enable the flap table to require less power for rotating the top board and to avoid shock when the top board is rotated by minimizing its size and simplifying its structure.

Torsion bar 51 provided along the center line P1 of the rotation of the top board 20 and a first supported member of the two supported members on the torsion bar 51 are supported by a first bar holding metal 52 to support it by restricting the rotation and a second bar holding metal 53 so that the second supported member may rotate with the rotation of the top board 20. The torsion bar 51 is distorted wherein torques N1 and N2 act, which elastically energize the top board 20 in the opposite direction of the torque generated by the gravity of the top board 20 in the top board rotation mechanism, when the top board 20 is in a horizontal position or in a standing position. It is also possible to employ a spring mechanism instead of the torsion bar 51.
